"If you download potentially copyrighted software, videos or music, your Internet service provider has been watching, and they're coming for you. Specifically, they're coming for you on Thursday, July 12. That's the date when the nation's largest ISPs will all voluntarily implement a new anti-piracy plan that will engage network operators in the largest digital spying scheme in history, and see some users' bandwidth completely cut off until they sign an agreement saying they will not download copyrighted materials." One day, years from now, historians are going to debate whether this was the point of no return.

We do have bittorrent peer-to-peer encryption implemented in most popular clients at the moment; even enabled by default in some. However, while protecting from simple traffic monitoring, it does not (or simply practically cannot) provide any form of peer authentication, hence it is vulnerable to man-in-the-middle attacks.

What I'm really curious about is - whether it is legal for ISPs to execute large scale network attacks on its users when it is clearly NOT in interest of national security?
